Question

x2+2ax-b2-2ab ? answer​

Answer 1

Answer:

Faxtorisation of x²+2ax-b²-2ab

=(x-b)(x+b+2a)

Step-by-step explanation:

Given quadraticexpressionx²+2ax-b²-2ab

= x²+2ax-b(b+2a)

Splitting the middle term,weget

= x²-bx+(b+2a)x-b(b+2a)

= x(x-b)+(b+2a)(x-b)

=(x-b)[x+(b+2a)]

= (x-b)(x+b+2a)

Therefore,

Faxtorisation of x²+2ax-b²-2ab

=(x-b)(x+b+2a)
